Negative pressure concern

Hello guys, I built a custom watercooling loop a few months ago... but the more i look at it, the more I question my airflow decision...

I'd like to know what you guys think of my fan setup... I'm a bit concerned I might have negative airflow in my case - here's an MSPaint sketch (components with a waterblock on in red):

Do you think I should add a bottom intake fan?

Cheers!

Actually, my PSU airflow arrow is wrong. It takes air from underneath and expells it out the back... I'll have to amend that in MSPaint!

EDIT: sorted

It's a Corsair 750D case.
I kept the AF140's that were given with the case in front... I could swap them for a pair of SP140's indeed but I kept it like that mostly because of laziness!

I think I might swap the Bitfenix around indeed. Although one usually says the top fans should be exhaust fans, in this case I think the 3x120's at the top might just do that well enough, and I like the idea of blowing cooler air directly onto it.

Lazy might have been too strong a word!

Rather eager to get the build done asap! I'll probably swap those AF's out for SP's in the near future. Good point on the dust filter.

EK's PWM version of the Laing D5. It's just really strong and reliable. Got the EK VRM block, EK Evo Supremacy CPU block, EK full cover GPU blocks (connected with a parallel terminal). Works a treat. Using a separate res as well. Here's a picture of the pc while I was still building it (no real cable management yet and still had the ugly white fan on top):

The 750D is a nice case but it is not massive. Had to do some proper space management.

The third GPU is dead, unfortunately... Rust in pieces. The idea is to get a new, better GPU a few months down the line. I had these 280x's lying around from an old build.
